  2. 2. What / Why / How • Is it possible to provide satisfactory experimental experiences in a remote learning environment? • How can a remote lab handle a massive environment ? • Is VISIR a tool suitable for teaching or complementing electronics learning process ? Remotely ? Face-to-face ? • Can become remote labs a stand-alone learning tool or do they need to be a part of a more complex system to achieve the learning goals they are able to provide ? Need some collaborative tools ? • Is possible to replicate the VISIR network in emerging countries ? And federate them ?

  7. 7. A remote lab? • A remote laboratory is a tool which combines software and hardware to allow students to access to real equipment, instruments and components remotely through the Internet • The main advantage of remote labs, when compared with traditional laboratories, lies in its availability that has neither temporal nor geographical restrictions • Main disadvantage are maintenance and 100% availability
  8. 8. What is VISIR ? Virtual Instrument System In Reality • VISIR is a remote laboratory for wiring and measuring electronics circuits on a breadboard remotely • VISIR allows realizing real measurements on physical equipment • The entire equipment is controlled by LabVIEW server software • The wiring mechanism is developed by means of a relay switching matrix connected to a PCI eXtensions for Instrumentation (PXI)
  9. 9. What is not VISIR? • VISIR is not a simulation software or a virtual lab; there is a physical limitation since it does not allow an indeterminate number of concurrent users • VISIR is not a lab to carry out any type of experiment; for example, destructive experiments are not allowed because all experiments must be reusable • VISIR is not an instructor; The measurement server acts as an instructor to avoid hazard circuits but it lacks of assessment and evaluation for teachers or guidance for students

  12. 12. Scalability!! • VISIR has some features that collide with a massive use or a MOOC: The intrinsic limitations of a real laboratory such as VISIR collide with one of the most relevant features that any MOOC should achieve: scalability • An undetermined number of users can access VISIR’s simulated workbench (it’s a server limitation as in other systems), but … • A maximum of 60 users can simultaneously perform measurements; more accesses to the measurement instruments collapses VISIR
  13. 13. Physical constraints Furthermore, for an optimal immersion, the number of concurrent users should not exceed 25 to obtain an adequate response time in continuous measuring (for occasional measures this factor is not critical) request muestra1 Gráfico de Dispersión 52 62 72 82 92 102 maxlist Gráfico de Dispersión 0 400 800 1200 1600 2000 2400 maxlist Gráfico de Dispersión 2080 2100 2120 2140 2160 2180
  14. 14. Bookings system settings Initial settings: • 2 simultaneous turns booked (variable) • 16 turns per course (variable) • 60 minutes per turn (fixed) • 16 concurrent users (variable); up to 384 turns every day Going to the limits (60 concurrent users): up to 1440 turns every day avoiding the risk of collapsing VISIR
  15. 15. New replications (I) Hardware, software and educational uses support (VISIR+): • Share publications and tutorials regarding the use of VISIR • Share the use of VISIR remotely to allow access • Start a first time face-to-face experience with decision making teachers and academic administrators regarding feasibility and best practice • Start several synchronous sessions (using some collaborative environment, like Moodle, videoconference facilities, etc.) with the new teachers and personnel involved in the new deployment to allow a fast starting access of the system
  16. 16. New replications (II) Hardware, software and educational uses support (VISIR+): • Develop face-to-face delivery with people involved in the on- site implementation as well as with new target institution members in the area of the local University • Have a local experience inside the classroom on the use and development of the educational implementation • Develop and extend the teaching experience from the local institution to all the core new institutions in the local area • Realize a formal evaluation and quality assurance of the process
  17. 17. New replications (III) UNED-Santiago del Estero collaboration: • Distance and on-line training • Face-to-face training Participant Institutions UNED & UNSE Local coordinator Rubén Fernández Members from EU HEI Manuel Castro & Félix García Loro Members from LA Institution/s Rubén Fernández, Héctor Paz, Mario Gómez, Fernando Soria City Santiago del Estero Dates (2016) September12th, 13th, 14th, 15th and 16th Total number of turnsa 8 Number of attendants 31 Attendees’ institutions Universidad Nacional de Santiago del Estero, Universidad Católica de Santiago del Estero, Universidad Nacional de Salta, Universidad Nacional de Tucumán, Universidad Tecnológica Nacional, Facultad Regional de: Buenos Aires, Delta, Paraná, Escuela de Educación Técnica Nº 8 IRICE member in person María Isabel Pozzo News on the web Link Faculty in UNSE: http://www.unse.edu.ar/index.ph p/editar/2963-se-dictara-taller- internacional Link home UNSE: Taller de capacitación Own VISIR? No Technical Training Action No
  18. 18. Outcomes (I) • The integration of remote laboratories in online learning environments, together with good practices in designing practical experiences, reduce the disadvantages of remote laboratories compared to in-person laboratories, without leaving behind their inherent advantages • Strategy of using diverse and complementary options in the same course (as in-person laboratories, remote laboratories and/or simulators) provides a broad range of capabilities and an easier assimilation of the experimental advantages
  19. 19. Outcomes (II) • Students have been able to complete the different activities and tasks from different courses and educative platforms, to interact with the remote lab. So, for students, the different systems used have accomplished its function: to provide the remote laboratory along with theoretical contents. • Previous experience for the UNED system implementation, communities and platform, aLF and INTECA videoconference system, allow the implementation of the remote laboratories as well as the support systems inside MOOCs
  20. 20. Outcomes (III) Advantages Disadvantages Simulator Flexible, generic, accessible More relaxed attitude It prepares for the real lab Everything works Complexity Virtual lab It simulates something real It’s specific It depends on the internet Online lab It simulates something real through Internet No specific setup or configuration Internet bandwidth use Remote lab It’s real Access to expensive equipment I can see what others do. Safe design It needs less physical space Users’ inversion is smaller. It may not work or it may not be maintained. It relays on internet connection. They do not seem real They are usually unique users They may get burned Software messages
  21. 21. Next steps: PILAR • Building a reliable, highly available, unique international VISIR platform federation, that integrates all the different resources used by VISIR in each of the partners • Federation will be completely opened to other partners, allowing to extend the capabilities of PILAR to much more interested educational institutions • Building a set of remote practices, based in this new platform • Those new remote Practices must allow, in a transparent way, the use of the best set of remote learning services available

  23. 23. Conclusions • Remote laboratory VISIR has shown the ability to perform its activity inside classrooms as in massive environments remotely • Experimentation and VISIR remote lab have been an attraction for teacher’s and students’ enrollment • The replication of new VISIR nodes are on-going • VISIR+ are expanding the VISIR network in South-America • PILAR is federating and incresing collaborative functionalities
